Most of this paper is dedicated to how information is presented to the user; user input is of secondary concern. There are several reasons for this. While most software today is event-driven, the Electronic Broadsheet is a contiguous process that can run without any user involvement. The newspaper will update itself much like a traditional newspaper will be delivered to subscribers weather they read yesterday's edition or not.

Also, an important part of the Newspace project is the user modeling [Orwant 91]
. The system keeps a dynamic model of each reader and consults the model when selecting what news to present. The more the system knows about the user, the less the uses needs to tell the system.

However, to adapt to a user's changing interests and habits, the system needs user feedback. Ideally, system feedback should be transparent to the user. The system should use eye tracking and gesture recognition as input channels, but this kind of user interface technology is not mature enough yet. We therefore have to settle for traditional explicit methods; the current configuration includes a mouse as pointer device.
